FOSTER, OF JAMESTOWN, NEW YORK, ASSIGNOR T0 JAMESTOWN METAL EQUIPMENT COMPANY, INC., 0F JAIWESTOWN, NEW YORK, A CORPORATION OF NEW YORK RADIATOR Application filed November 28, 1930. Serial No. 498,543.

The invention relates to improvement in radiators and more particularly to a filler and overflow pipe therefor.

Heretofore radiators have been fitted with a filler pipe mounted centrally of the upper tank of the radiator. An overflow pipe terminating in the filler pipe was projected through the upper tank and thence through the side of the tank or through the core to a point beneath the radiator. Under conditions when an automobile motor overheats, or during winter driving, the overflow pipe is required to carry ofl extremely hot water or, in some instances, steam, acting as a relief for any pressure built up in the cooling system. By reason of the intense heat and also through vibration necessanly produced during operation of a motor vehicle, the overflow pipe cracks or becomes loosened from its support within the upper tank, radiator core, or both and causes a leak to occur in the system. Further object on to the provision of an overflow pipe which is supported in the radiator obtains when the system freezes and causes the radiator or water tank to draw away from the overflow pipe, producing a gap through which leakage may occur.

Since considerable cost is involved inrepairing a leaky radiator, any practical means by which to overcome and prevent the above difficulties is desirable. The present invention is therefore directed to such a device and has for its principal object the provision of a radiator with an external overflow pipe.

Another object of the invention lies in the provision of a radiator having an offset filler pipe by reason of which an overflow pipe may be directed into said filler pipe through the bottom wall.

Other and further objects of the invention will be apparent from a consideration of the following specification which is taken in conjunction with the accompanying drawings, and in which Fig. 1 is a fragmentary front elevation of a radiator embodying one form of this invention Fig. 2 is a side elevation of the structure in Figure 1, showing the oflset filler pipe and overflow pipe;

Fig. 3is an enlarged side elevation of the filler pipe; a

with base and overflow pipe attached thereto; Fig. 5 is a plan view of the filler pipe base; and f Fig. 6 is a side elevation of the base shown in Figure 5, parts being broken away to dis close the overflow connection.

Referring to the drawings, this invention is shown mounted for use in a radiator generally indicated by the reference numeral 10. The radiator comprises a core 11 and upper water tank 12. Centrally of the ends and overhanging the front edge of the tank is a filler pipe 14.

The filler pipe comprises an annular ring 16 closed by the base element 18. The base 18 is formed with an annular flange 20 which defines the circumferential edge of the wall 21. A semi-circular opening 23 is produced in the wall 21. Centrally between the'flange 20 and the inner edge 24 of the opening 23 is a further opening 25 of considerably lesser size. This opening is produced with upwardly and downwardly projec ing flanges 26 and 27 which meet in the plane of the wall 21, substantially. on the center line of the opening 25. In this fashion the opening Fig. 4: is a side elevation of the filler pipe t 25 is formed with supporting flanges adapt- To assemble the structure the ring 16 is.

mounted in the base 18, being secured thereto by soldering. An overflow pipe 28 is engaged with the flanges 26 and 27 of the opening 25, being secured thereto in any suitable manner as by soldering. The filler assembly is mounted on the upper face of the tank 12, substantially as shown in Figure 2. The opening 23 in the filler lies over the corresponding opening in the tank 12, whereas, the opening 25 and attached pipe project beyond the front wall of the tank 12. The pipe 28 is carried to one side of the core 11 and for the purpose of concealment is ofiset and projected down toward the bottom of the radiator adjacent the end wall of the core.

While applicant has shown and described but one modification of a structure by which to carry off the overflow from an automobile radiator without projecting the overflow pipe through the radiator, it will be obvious to those skilled in the art that certain modifications of the structure may be made without departing from the spirit and scope of the invention as set forth in the hereunto annexed claims.

Having thus set forth my invention what I claim as new and for which I desire protection by Letters Patent is 1. In a radiator, an upper ta-nk, walls defining an inlet opening adjacent the forward edge of said tank, a filler pipe having a base partly supported on said tank, walls defining an opening in said base, said pipeopening registering with said tank opening, flanges defining a second opening in said base, an overflow pipe projected through and engaged with the flanges of said secondopening, said overflow pipe being connected directly with the exterior of said radiator.

2. A radiator filler pipe having a base partly overhanging one vertical face of a radiator, walls defining a filling opening in said base registering with an opening in said radiator, flanges defining a second opening in said base, and an overflow pipe projected through said second opening and joined to said flanges.

3. In a radiator having an inlet opening, a filler pipe, a base closing one end of said pipe, walls defining openings in said base, an overflow pipe connected with one of said openings, the other of said openings registering with said radiator opening.

4. In a radiator having an inlet opening, a filler pipe joined to and overhanging'one vertical face of said radiator, a baseclosing one end of said pipe, walls defining an opening in said base in register with said radiator opening, and overflow means direct- 1 ly connecting said filler pipe with the exterior of said radiator.

5. In a radiator havlng an inlet opening,

i a filler pipe joined to and overhanging one FRED L. FOSTER.
